Question 301693: How do you solve the following A Social Security is a code made up of 3 digits - 2 digits - 4 digits. If repetition of numbers were not permitted in ss numbers how many different ss # would be possible? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! It's 9 digits.
The 1st can be one of 10 (assuming it can be zero).
Then 1 of 9, 1 of 8, etc
--> 10*9*8*7...
= 10! (10 factorial)
